产品介绍

此系列产品为介孔二氧化硅包覆上转换纳米颗粒。材料组成为NaYREF4 (RE:Yb, Er, Tm, Gd, Mn, Lu)，最佳激发波长为975 nm。敏化离子为Yb3+，激活离子为Er3+或Tm3+。通过调节各离子掺杂浓度，产品在特定波长的发光已得到优化。纳米颗粒粒径均一，发光量子效率高，光稳定性好。该产品不仅可以很好地分散在水介质中，由于介孔SiO2的强吸附能力，产品可以直接作为光敏剂和其他药物的载体，因而可直接用于基于上转换技术的光动力疗法以及抗癌药物和生物分子的光控远程释放。 This product contains mesoporous silica coated NaYREF4 (RE:Yb, Er, Tm, Gd, Mn, Lu) nanospheres. The UCNs can be well dispersed in aqueous media.The sensitizer is Yb3+, and the activator is Er3+ or Tm3+. The doping concentrations are optimized, leading to strong upconverted emissions at specific wavelengths. The UCNs are of high quantum efficiency and very photostable. Due to the adsorption capacity of mesoporous layer, these nanospheres can be used as nanocarriers of photosensitizers in photodynamic therapy and of biomolecules in photoactivation triggered by near infrared light.
